Power Drive Units

Ancra 3-inch Power Drive Units (PDU’s), by Ancra International

  

 

 

 

 

    Ancra 3-inch Power Drive Units (PDU’s) are designed as drop-in replacements for original equipment and aftermarket PDU’s on B767, B777 and B747Fs, without modification to the aircraft structure or electrical connections. Ancra has also developed a 2-inch PDU for lower deck applications. These self-lifting, low-profile units weigh less (9 pounds) are lower cost alternatives to other in-service PDUs, and feature:

 

  • ● High-traction force and controlled vertical force for maximum grip in wet or dry conditions
  • ● Single-drive roller that doesn’t retract during direction reversal, offering continuous control
  • ● Field replaceable electrical cable, environmentally sealed electronics, motors and gearing to aid in maintenance
  • ● Dual brushless DC motor operated by solid state power switching modules with redundant optical sensors and scrub sensors to minimize wear and tear on the roller rubber
  • ● Sophisticated control system to detect soft and hard pallet characteristics for optimized traction and reliability
